    Abstract: Systems, methods, and computer program products implementing hybrid file structures for data storage are provided. One embodiment of a method performed in a computer-based storage system includes writing a file as data blocks in an array of storage devices. The method includes associating the data blocks with metadata related to at least one location in the array of storage devices for later access to the data blocks. The file is represented as a hierarchical data structure having a plurality of nodes. A first portion of nodes has a first span type, and a second portion of nodes has a second span type. The data structure includes a buftree. The first span type includes a fixed-span type. The second span type includes a variable-span type.

    Abstract: Techniques to clone a writeable data object in non-persistent memory are disclosed. The writeable data object is stored in a storage structure in non-persistent memory that corresponds to a portion of a persistent storage. The techniques enable cloning of the writeable data object without having to wait until the writeable data object is saved to the persistent storage and without needing to quiesce incoming operations (e.g., reads and writes) to the writeable data object.

    Abstract translation: 公开了在非持久存储器中克隆可写数据对象的技术。 可写数据对象被存储在对应于持久存储器的一部分的非永久存储器中的存储结构中。 该技术能够克隆可写数据对象,而不必等到可写数据对象被保存到永久存储器中,而不需要暂停对可写数据对象的传入操作(例如,读和写)。

    Abstract: A request is received to remove duplicate data. A log data container associated with a storage volume in a storage server is accessed. The log data container includes a plurality of entries. Each entry is identified by an extent identifier in a data structures stored in a volume associated with the storage server. For each entry in the log data container, a determination is made if the entry matches another entry in the log data container. If the entry matches another entry in the log data container, a determination is made of a donor extent and a recipient extent. If an external reference count associated with the recipient extent equals a first predetermined value, block sharing is performed for the donor extent and the recipient extent. A determination is made if the reference count of the donor extent equals a second predetermined value. If the reference count of the donor extent equals the second predetermined value, the donor extent is freed.
